Retroperitoneal Cyst of Mullerian Type.

ABSTRACT

Retroperitoneal mullerian cysts are rare, benign neoplastic cyst of urogenital subtype. They are usually asymptomatic and may present with symptoms if they grow considerably in size with pressure over the adjacent organ or follow infection, hemorrhage or rupture. Histologically, these cyst are lined with benign ciliated columnar epithelium. We present the case of a 30-year-old female with history of abdominal distension and epigastric pain. The mass excised was in retroperitoneal space and microscopic examination revealed benign cyst of mullerian origin.
